A Linear Variable Differential Transformer (LVDT) is a precision electromechanical sensor used to measure linear displacement by converting mechanical motion into a proportional electrical signal. It belongs to the family of inductive transducers and operates without physical electrical contact between moving parts, which is a key reason for its durability and accuracy. In modern engineering […]

PIR Motion Sensor Circuit with 555 Timer IC
Let’s designing a PIR motion sensor circuit that uses a Passive Infrared (PIR) sensor to control a buzzer through a 555 timer for motion detection applications. Here’s a step-by-step guide to creating this circuit: Working Principle of PIR Motion Sensor: A Passive Infrared (PIR) motion sensor detects motion by sensing changes in infrared radiation. Here’s […]
